i BOTTLESEALING' AMACHINE.

Specification of Letters Patent.

Application ined may 2s, 1917. serial No. 171,387.

vTo all whom t may concern:

Be it known that I, AMos CALLnsoN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of `New York,have invented certain new and In the accompanying drawing, the viewshows in vertical section a bottle sealing ma chine embodying myimprovements.

The base a; table b; pillar 0,' head d; carrier e on which is bolted orotherwise secured the element f on which are suitably arranged thepressure applying sealing head g and other parts, said carrler beingmovable up and down oscillatory on the pillar c; the

horizontal drive shaft h journaled in the head; the lever c' fulcrumedin the head and having asliding engagement with the upstanding stud j onelement f; and the rotary bottle advancing turret c journaled on thebase a concentric with the pillar are or may be, except as hereinafterindicated, all substantiall the same as in my Patent No.

The carrier e has an inward projection Z and a stud m, equipped with aroller n, the pillar being formed with an opening o to ac-v commodateand permit movement of the stud and projection with the carrier as thesame moves up and down and transversely, as will be explained. Securedto the projection Z-by the bolt p, or otherwise, is a sleeve g formingin effect a downward extension of the carrier, it being-concentric withthe pillar and ided by a bearing 'l' keyed into the foot of t e pillar.

A long shaft s extends through the head d, an inwardly projecting arm tof the pillar (in which arm the shaft is in effect stepped by virtue ofits shoulder t) and the sleeve g, being threaded at its lower end andsupported against lateral movement at its upper.

end by a plate u suitably secured on the head d. On the lower threadedend of this shaft is screwed a long nut 7) having a shoulder 'w at itslower end and thereby forming a step for a spring which is coiled abovethe nut and extends up into the sleeve, the upper end ofwhich is reducedand affords at y a thrust bearing for the spring. 1t will be seen, inview of the foregoing, that the carrier is yieldingly supported by thespring Vin turn supported by the nut or step o which is screwed on theshaft 8 and therefore virtually becomes a fixed part of the frame. Thenut is adjustable by turning it on the threaded portion of the shaft,whlch may be held against rotation for this purpose by the set screw z.1t is preferred that'the upper end of the sleeve g be' afforded abea-ring, as at 2, on the shaft.

Concentric with the shaft s is a hollow shaft or sleeve 3 penetratingthe head; the shaft 3 is kept from vertical movement by an anti-frictionbearing 4 arranged thereon against a shoulder 5 and bearing against thelower side of the head and an anti-friction bearing 6 arranged thereonabove and fheld against the head by a cam structure 7 keyed on saidshaft, such cam structure being adapted, when rotated, to oscillate thelever 'i and hence the carrier substantially the same as in my patentreferred' to./ Below the head shaft 3 carries a barrel cam 8 whosecalnway 9 faces and is engaged by the roller n on stud m of the carrier.The shaft 3, and consequently cam-structure 7 and cam 8, is rotated fromshaft k through a Worm 10 thereon and a worm-wheel 11 suitably' fixed onshaft 3.' v

The turret c-may be rotated from shaft h through a vertical shaft 12,suitably journaled in the head d and table b and provided with aworm-wheel 13 meshing with the worm 10 and a pinion 14 meshing with gearteeth 15 on the turret. 4

The operation will be apparent. On shaft It being rotated, while theturret is rota tively driven therefrom so as to advance the bottles in acircular course around the base of the pillar, structure 3, 7, 8 isdriven from shaft h, causing, through lever c', carrier e to oscillatearound shaft s as an axis and the carrier at intervals to movedownwardly, to perform the sealing thrust, the return movement of thecarrier being effected by the spring the resultant of these movements ofthe carrier being substantially the same as in my aforesaid patent. rlhetension of the spring is designed to be adjusted so as to keep theroller n against the face of cam 8, eliminating lost motion, byadjusting the nut or step 'v on the threaded shaft.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent is l. ln combination, a xed structure and areciprocatory structure guided by said fixed structure and having apressure applying head coactive with said lixed structure to exertpressure on a container, and means to reciprocate the second structureincluding a rotary cam device journaled in the first structure andengaging the second' structure and adapted to move the latter in onedirection and spring means pressing the second structure in the otherdirection, the axis of rotation of the cam and the thrust axis of thespring means being substantially c'oincident and extendinglongitudinally of the thrust-line of said second structure, said headbeing odset with respect to the irstnamed means.

2. ln combination, a ixed structure and a reciproca-tory structureguided by said fixed structure and coactive therewith to exert pressureon a container, the second structure being also rotatable on an axislongitudinal of its line of thrust movement, and means to reciprocatethe second structure including a rotary cam device journaled in thelirst structure and engaging the second structure and adapated to movethe latter in one direction and spring means pressing the secondstructure in the other direction, the axis of rotation of the cam andthe thrust-axis of the spring-means being substantially coincident withthe axis of rotation of said second means.

8. in combination, a xed structure and a reciprocatory structure guidedby the iixed structure and coactive therewith to exert pressure on acontainer, a cam engaging the reciprocatory structure and adaptedLacasse to move the saine in one direction and journaleduon an axisextending longitudinallyof thepath of movement of said reciprocatorystructure, and a spring interposed between said-structures and adaptedto move the reciprocatory structure in the other direction, one of saidstructures having springadjusting means rotative on said axis.

4. 'ln combination, aliixed structure and a reciprocatory structureguided by said fixed structure and coactive therewith to exert pressureon a container, the first structure having a shaft extendinglongitudinally of the thrust of the second structure and a1 stepadjustable longitudinally of and on the shaft, and means to reciprocatethe second structure including a cam device journaled in the irststructure and engaging the second structure and adapted to move thelatter in one direction and spring means bearing against said step andpressingthe second structure in the other1 direction.

5. ln combination, the frame having an upstanding hollow pillar, acarrier movable up and down on and arranged exterior of the pillar, saidframe having a step axial of the pillar, means to move the carrier inone direction including a rotary cam within and coaxial with the pillarand engaging the carrier, and a spring Within the pillar pressing thecarrier in the other direction and bearing against said step.

6. ln combination, the frame having an upstanding hollow pillar, acarrier movable up and down on and arranged exterior of the pillar, saidframe having a. step axial and adjustable longitudinally of the pillar,means to move the carrier in one direction including a rotary cam withinand coaxial with the pillar and engaging the carrier, and a springwithin the pillar pressing the carrier in the other direction andbearing against said step.

in testimony whereof l aiiix my signature.
